Sanchez, Ramon Cota's (Billy Drago) guard in the camo shirt, use IMI Uzis during the car chase. Also seen held by Chuck Norris on the film's poster. He never uses it during the movie however.

IMI Micro Uzi

A two tone Micro Uzi (like as seen in Total Recall and The Running Man) were used by some of Ramon Cota's assassins to massacre the DEA agents at a carnival the beginning while disguised as party-goers. Carlos (Rick Prieto) uses a two-tone black and nickel one.

Heckler & Koch MP5A3

Two Delta Force members take cover behind a wall during the firefight at Cota's mansion, H&K's in hand.

Kalashnikov-type assault rifle

Norinco Type 56 (Imported into the U.S. as the Norinco AKS-47 or AKS-47 Sporter) - 7.62x39mm. Rather than having the underfolder pig sticker Bayonet assembly, this has the standard Bayonet lug underneath the gas block as the AKM and later variants.

One of the guards at the drug plant fires on the Delta Force helicopter with his AKM during the battle.

The guard hefts his M16 as he confers with Cota. A grenade is also visible in this shot on the man's vest.

A guard fires at the Delta Force helicopter with his M16 when the Americans raid the drug factories.

A guard at the mansion stands at a balcony with his M16 slung over his shoulder.

In a continuity break, when McCoy (perched on a light fixture) pulls the guard off the balcony, the man's slung M16 disappears. It didn't fall to the balcony when he was seized, because it isn't there in the next shot when McCoy climbs up. One could also argue McCoy would've appropriated it if it was there, too.

During the battle at the village, McCoy grabs an M16 off of a guard he killed.
